Description

Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise.

Maintain and exercise incident response plans 1, including the management of 'gold-copy' back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.

Techniques Addressed by Mitigation

Name	Use
Data Destruction	Utilize central storage servers for critical operations where possible (e.g., historians) and keep remote backups. For outstations, use local redundant storage for event recorders. Have backup control system platforms, preferably as hot-standbys to respond immediately to data destruction events.2
Denial of Control	Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise. Maintain and exercise incident response plans1, including the management of "gold-copy" back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.
Denial of View	Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise. Maintain and exercise incident response plans 1, including the management of "gold-copy" back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.
Loss of Availability	Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise. Maintain and exercise incident response plans 1, including the management of "gold-copy" back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.
